Slow-Cookin' Pulled Chicken

I have made this recipe many, many times. It's to the point where friends and family request it regularly. It's quick, easy, and can feed a family for days. I found the recipe thanks to Hungry Girl at www.hungrygirl.com. It's an awesome site if you have not checked it out before.

Ingredients

1 1/2 lb boneless, skinless chicken breast
1 cup canned tomato sauce
1/2 cup ketchup (I prefer reduced sodium OR hot and spicy)
2 tbsp plus 2 tsp brown sugar (not packed)
2 tbsp plus 2 tsp cider vinegar
2 tsp (or more) garlic powder
red pepper flakes to taste
(I also like to use the Crock Pot Liners by Reynolds)

Directions
--Place all ingredients except for the chicken in a crock pot (lined optional). Stir until mixed.
--Add chicken and coat well with sauce.
--Cover and cook on high for 4 hours or on low 7-8 hours.
--Pull apart the chicken breasts with a couple of forks.
--Serve loose or on buns. I prefer the whole wheat reduced fat ones by Sarah Lee)
